Navajo Tech Awarded $4.4M for STEM Education, Rural Networks

(TNS) — Navajo Technical University is the recipient of two grants from the National Science Foundation. One award will sustain a project that focuses on increasing the number of Native American students pursuing degrees in STEM.

That amount is $4 million, and it will benefit the Vision for Excellence at Navajo Technical University in Research and Education in STEM, a project managed through a partnership between NTU and Harvard University through its Materials Research Science and Engineering Center.

Is Global Warming Melting Antarctica's Ice?

Although researchers have known for decades that climate change is causing some ice to melt in Antarctica, the reasons behind these changes have been a hot-button issue in scientific, environmentalist and political circles.

But recent evidence suggests that global warming is behind the meltdown.

"It is very likely that this is a result of global climate change," said Erin Pettit of the Department of Geology and Geophysics at the University of Alaska Fairbanks. "From a number of different data sets, including ice cores, we know that the temperatures in the Antarctic Peninsula and the western half of the Antarctic Continent have been warming over the last several decades faster than in the past.

How Would Just 2 Degrees of Warming Change the Planet?

The Earth is home to a range of climates, from the scorching dunes of the Sahara to the freezing ridges of Antarctica. Given this diversity, why are climate scientists so alarmed about a worldwide temperature increase of just 2.7 degrees Fahrenheit (1.5 degrees Celsius)?

Changing the average temperature of an entire planet, even if it's just by a few degrees, is a big deal, said Peter deMenocal, a paleoclimate scientist at Lamont-Doherty Earth Observatory at Columbia University in New York.

Could climate change make humans go extinct?

The impacts of climate change are here with soaring temperatures, stronger hurricanes, intensified floods and a longer and more severe wildfire season. Scientists warn that ignoring climate change will yield "untold suffering" for humanity. But if things are going to get that much worse, could climate change make humans go extinct?

Scientists predict a range of devastating scenarios if climate change is not kept under control, but if we just consider the direct impacts, then there's some good news; it's unlikely to cause our extinction.

These 3 energy storage technologies can help solve the challenge of moving to 100% renewable electricity

In recent decades the cost of wind and solar power generation has dropped dramatically. This is one reason that the U.S. Department of Energy projects that renewable energy will be the fastest-growing U.S. energy source through 2050.

However, it’s still relatively expensive to store energy. And since renewable energy generation isn’t available all the time – it happens when the wind blows or the sun shines – storage is essential.

DOE Announces Nearly $34 Million to Advance Waste and Algae Bioenergy Technology

WASHINGTON, D.C. – The U.S. Department of Energy (DOE) today announced nearly $34 million in funding for 11 projects that will support high-impact research and development to improve and produce biofuels, biopower, and bioproducts. These biomass resources, otherwise known as feedstocks, can be produced by municipal solid waste (MSW) streams and algae and converted into low-carbon fuels that can significantly contribute to the decarbonization of transportation sectors that face barriers to electrification, like aviation and marine. By lowering the carbon footprint of the transportation sector, biofuels will play an important role in reaching the Biden-Harris Administration’s goal of achieving net-zero emissions by 2050.

Better Bioblendstocks for Cleaner Diesel Vehicles

There’s no driving around it: most vehicles on the road today are still powered by gasoline and diesel fuels that create and emit greenhouse gas emissions. But new fuel blendstocks from biomass and waste resources, combined with advanced engine designs, are bringing us ever closer to a vision of clean transportation. Achieving this vision is critical for meeting our nation’s renewed goals for reducing greenhouse gases in the atmosphere to address climate change.

Planting forests may cool the planet more than thought

Planting trees and replenishing forests are among the simplest and most appealing natural climate solutions, but the impact of trees on atmospheric temperature is more complex than meets the eye.

One question among scientists is whether reforesting midlatitude locations such as North America or Europe could in fact make the planet hotter. Forests absorb large amounts of solar radiation as a result of having a low albedo, which is the measure of a surface’s ability to reflect sunlight. In the tropics, low albedo is offset by the higher uptake of carbon dioxide by the dense, year-round vegetation. But in temperate climates, the concern is that the sun’s trapped heat could counteract any cooling effect forests would provide by removing carbon dioxide from the atmosphere.

But a new study from Princeton University researchers found that these concerns may be overlooking a crucial component — clouds. They report in the Proceedings of the National Academy of Sciences that the denser cloud formations associated with forested areas means that reforestation would likely be more effective at cooling Earth’s atmosphere than previously thought.

July 2021 was Earth’s hottest month ever recorded, NOAA finds

If you thought this July was just toasty, you probably didn’t realize you were living through the hottest month in modern history. On Friday, the National Oceanic and Atmospheric Administration declared July 2021 the world’s hottest month in 142 years of records.

“In this case, first place is the worst place to be,” NOAA Administrator Rick Spinrad said in a statement. “This new record adds to the disturbing and disruptive path that climate change has set for the globe.”

The world watched in July 2021 as extreme rainfall became floods that washed away centuries-old homes in Europe, triggered landslides in Asia and inundated subways in China. More than 900 people died in the destruction. In North America, the West was battling fires amid an intense drought that is affecting water and power supplies.
